PORTABLE GRAIN-DUMP.

- SPECIFICATION forming part of Letters Patent $10,760,862, dated May 24, 1904.

Application filed-January 4, 1904. Serial No. 187,744. 2 (No model.)

To all whom it may concern:

Be it known'that I, SAMUEL GUTH, ,a citizen of the United States,.r e'siding at Washington, in the county of Taz'ewell and State of Illinois, have invented certain new and useful Improvements in Portable Grain-Dumps; andI 'do hereby declare that the following is a full,

clear, and exact description of the invention, which will enable others skilled in the art' to which it appertains to make and use the same.

This invention pertains to portable grain dumps, and has for one of its objects to'produce an easily and freely operated grain-dump for unloading wagons. p

It further relates to a combined grain dump and elevating device bywhich the grain emptied. from the wagon can be elevated to any desired receptacle.

The invention also relates to certaindetails of construction, as will be. pointed out in the specification and in the accompanying claims.

- In the annexed drawings, Figurel is aside contents of the wagon is dumped. Fig. 4 is a front View of a yoke employed on'the con- "veyer shown in Fig. 4. Fig. 5 is a side view of-a portion'of the head of the elevator, showing adjusting means for-a conveyer shaft.

Fig. 6 is a perspective View of an adjustable member shown in Fig. 5. Fig. 7 isa perspective view of means for carrying the front wheels of they wagon. a

- A indicates the platform of the dump,-con- Si l ing of the usual sills and fiooringand end approaches, the latter being indicated by B B.

At one side of' the platform a 'framingis extended, consisting of the beams C C. Mounted across these said beams in suitable bearings is a shaft D, forming a pivot for and driving means for an elevator E, whose lower extremity lies between said beams C C, as shown.

The elevator is provided with the usual chains and drags, all of which are too well known to require more description here. Pivoted v v v [adjacent to the elevator. Fig. 2 is a plan View thereof.-

to each beamC isan upright F, one being at each side of the elevator, the upper ends approaching each other and carrying a grooved.

pulley G, over which runs a rope or cable, one end of which is connected to a bail H toward the head of the elevator,'the other end passing around a Windlass-roller I on a shaft 'J, mounted on the elevator. On the same shaft is aratchet-wheel K, while a pawl Lis carried on the side of the elevator in engagement with said ratchet, and it will be seen thatby turning the Windlass by means of its crank the head of the elevator may be raised or lowered, as desired, the arms F acting. as the support therefor. Said arms are slotted',.and a clamping-screw is provided at M, by which when the elevator is placed in the desired position can be secured. Overhanging the elevator-boot is a drag or conveyer N, which extends over the platform across the driveway, as indicated in Fig. 2. Said conveyer is pivotally carried at its end In Fig. 1 is an upright 0, secured rigidlyby means of a brace P. Bolted'to O isa 'castingQ, carrying a vertical shaft R, Fig.4, whose upper end is embraced by means of a boss S of a yoke T, Fig. 4. Beneath said boss the said shaft carries a gear-wheel U, which meshes with a gear-wheel'V, serving to operate thedrag-belt W of the conveyer, all of which is common to machines of this class. Thelower end of the shaft R carries a beveled gear X, which meshes with a similar wheel Y on a shaft Z,

whose one end rests in asocket 2 of the cast ing Q, Fig. 4, its opposite end being carried in a bearing 3 onone of the beams C. The outerend of said shaft Z is provided with a sprocket-wheel 4 for engaging with a similar wheel 5 on the shaft D by means of a chain a 6, Figs. 1 and 2. Thus mounted the conveyer If desired, a suitable support by which to hold that member from sagging and straining the gears and other parts at the pivoted end, all of which will be understood.

I now provide means for raising the front end of the wagon. This means consists, first, of a vertically-movable support for the front wheels. This said support is composed of two planks 7 and 8 of the platform, having beneath their ends blocks 9, said planks being hinged to the blocks, as shown at 10 in Figs. 1 and 7. The blocks are notched beneath the planks, as shown in Fig. 1, so that said planks will lie therein to thus form a depression in which the wheels will rest, as shown in broken lines in said Fig. 1. A yoke or bail 11 serves to support each block and is supported loosely from the end of a lever 12 to an upright 13 at each side of the platform. Pivoted at one end to said upright 13 is a rod 14, whose other end is suitably pivoted to said block 9, the purpose of which will presently appear. The free ends of the levers 12 loosely carry pulleys 15, through which runs a cable 16, one end being attached to the platform and the other end passing around a winding-drum 17 on a shaft 18, let into the planks of the platform, so as not to interfere with the driving of a wagon upon said platform. Said shaft 18 at one end is provided with a sprocket-wheel 19 and a ratchet-wheel 20, the latter being normally held from revolution by means of a pawl 21, pivoted on the platform and controlled by a pull-rod 22. The said sprocket-wheel 19 is connected by a chain 23 to a sprocket-wheel 24 on the shaft D, before described. The latter sprocket-wheel is secured to a sleeve 25, Fig. 3, carrying a portion of a friction-clutch 26, adapted to engage the drum 27 of such clutch, keyed at 28 to'said shaft D. Said sleeve 25 also carries a shifting ring 29, operated by means of a forked lever 30. The shaft D is driven by means of a pulley 31 and during constant revolution drives only the conveyer through the sprocket-chain 6 described. The sleeve 25, above described, being loose onsaid shaft D does not move until shifted toward the drum 27, which, as before explained, is fast on said shaft D. When shifted toward and into 27, the sprocket 2 1 is revolved, thus imparting movement to the shaft 18 to wind up the cables. When this takes place, the levers 12 are drawn down by means of the cables 16, thereby raising the opposite ends of said levers and raising the planks 7 and 8 described. When the said planks7 and 8 are at rest, they appear as shown in Fig. 1, Where they rest upon the beams of the platform. Now when raised the planks by gravity fall into the notches of the blocks 9, thus, as before explained, forming a lodgment for the wheels of the wagon. It is evident that if the wheels were-raised in a perfectly-vertical line the rear end of the wagon would necessarily be moved on its wheels first backward and then forward as the front wheels approach and pass a horizontal line passing through the center of the axle of the rear wheels; but since the levers 12 are pivoted behind the wheels, which they raise, said wheels will describe an arein their upward movement which practically is described from said rear axles, and in this way the said rear end of the wagon will remain in one position while in the act of dumping, except a pivotal one on its axles. In order to guide the blocks 9 in these movements, the said rods 14 are provided, and these serve to hold the blocks and planks horizontal and likewise answer to guide said blocks back between the under beams of the platform. At 32 is a hopper which is attached to the conveyer and adapted to receive the contents of the wagon. Also at 33 is designated a hopper at the opposite side of the conveyer, into which grain may be dumped from various receptacles when desired for other purposes than a grain-dump for wagons. In order to make the dump portable, I provide a pair of wheels 34:, which may be placed beneath the platform after raising one end thereof.

' At the head of the elevator the shaft 35 is extended beyond the said head and carries a beveled gear 36, with which meshes a similar gear 37 on a stub-shaft 39, having a bearing in a yoke 38, through which said shaft 35 also passes. 6, and clamped to the elevator-head by means of a bolt 10 in Fig. 5, so that any adjustment of the yoke may be had. The purpose of this is that a conveyer may be driven by means of the shaft 39, and in order that said shaft may be held horizontally at all times while the elevator is inclined at any height desired the yoke must be movable to permit said shaft 39 to be horizontal.

After raising the wagon to dump it, as described, it is only necessary to liberate the ratchet-wheel by withdrawing the pawl therefrom by means of the pull-rod 22 to permit the wagon to descend to its position for driving off of the platform, the clutch having been disengaged during or before the dumping action takes place. The said clutch may of course be held in engagement, so as to gradually raise the wagon as the grain passes therefrom, or may be used to elevate the wagon at once and then let the grain pass out as desired.

A point of advantage in my dump is the ease with which the carrying-wheels can be placed under the platform or removed therefrom. This is accomplished by the aid of the levers 12, together with two portable posts 41. These latter are set upon the ground immediately beneath the said levers 12 when it is desired to raise the platform to place the wheels in position. One of them is inserted between one of the beams C and the side of the platform, while the other is let down through an aperture near the opposite side of the platform at 41. Now it will be seen that Said yoke is slotted, as shown in Fig. 5

in drawing down the levers they will rest upon these posts 41, and a-continued winding of the cables 16will result in raising the conveyor be inserted or removed, as the case maybe.-

The posts 41 are then removed and placed where they can be used at a moments notice.

It is to be. understood, however, that any stick sufficiently strong ;can be employed. in. lieu of the posts, as shown.

journaled therein,.carries a sprocket-wheel 42, which by means of a sprocket-chain 43 drives alsprockt-wheel 44 on a conveyer 45, hung beneath the head of the elevator and into which the grain can be discharged. This conveyeris also shown in broken lines in Fig. 2. This construction isemployed when it is impossible or. inconvenient to get near the re ceptacle into which the grain is to be discharged, and it will be seen that with the said conveyer any remote place can be readily reached.

I do not wish to confine myself to the particular construction and arrangement of parts described and shown, as various changes may be made without departing from the spirit of the invention.-
